Why the upgrade not incoporate WAP 2.0 feature ? Probably because:
1. It's Marketing strategy;
2. Phone cannot hold all data to it's storage;
For reason number 2 seems like phone has different memory size, in fact both has exactly same memory, so maybe the explanation like this:
Just imagine your phone like your PC's BIOS, and you know when you upgrade your BIOS is simply to flash the phone, but do you know that not all Flash area is updated ? There is some small part area that not Flashable, the reason this one is the 'file system' area of the BIOS, so you cannot flash it, otherwise you will have dead mother board.
In T68m, maybe the case is almost same, since the memory management between T68m and T68i software is different (T68i using new dynamic shared memory), so in this case you can imagine that the 'core' is different, and unfortunately you cannot update the 'core' part (because it's the one who responsible to handling flashing sequence), then you must sacrifice this part to be not used on new system, so new software can be flashed to old system with making new memory system that lay in old system, this make the room more smaller cause old system cannot be deleted, and the difference with T68i, because it's already using new system.
For real example maybe like this, software has 1 MB in size, and the Flash ROM have 1,2 MB, but since 200 KB used for file system then only 1 MB can be used. For T68i which already have same system, it need only to inject to rest 1 MB space with it's software, but for T68m which using old system, it need to get new basic layer, that unfortunately cannot done by overwriting the system, so it will add about 200 KB on it's 1 MB space for system, leaving only 800 KB for software, so since space is not possible to inject all software to it then it sacrifice the WAP 2.0 part.
All above is my conclusion based on reading some statement from many party including SE FAQ and I try to conclude why it's not incorporate WAP 2.0, in case above both phone equiped with same 1,2 MB Flash ROM hardware, but the one can using it fully (T68i) and the other not (T68m).
Any correction and comment is welcome, since all above is my only my conclusion.

Hello Juming,
I think you may have a point here. However I found out that you can upgrade the "rom memmory" of the mobile but by using another cabel between phone and the PC than the one they have at the sevice point. I think that this may also explain why they were not ready to release the upgrade when the sw was ready to release in the T68I. SE needs a program to flash onto to the old t68m sw which "internally" changes the memmory management system in the "rom memmory" (as for the r380 conversion) and when that operation is completed you can flash the T68I "application" on to the phone. If you know somedbody who works at SE phone development they would probably be able to flash first the PDF file (product definition file) into the phone (using the lab equipment) and after that flash the T68I application program onto the phone (from EMMAII).
I am convinced that the programs will be identical for the T68I and the updated T68m because otherwise SE would have to maintain two program versions and that is not rational at all for the same HW base.
Just my speculations, comments are welcome of course.
Cheers

I e-mailed
about the 2.0WAP. They said that because the upgrade will make the T68m=T68i it will also contain wap 2.0.

wapmanse: I think you are right, I read about the conversion that will make the "m" identical to the "i". For one, the reason the menus and the T9 will be faster is that the file system will be updated (This i read at the swedish site:
www.mobil.se) and i assume it will be identical to T68i. Cause, why change file system to a diffrent one from the "i"?
Second, at the SE faq section they say that the T68m will be identical to T68i after the conversion, and i don't think SE would make such a fatal mistake saying that they will be identical and forget about the wap version.

I think SE means that wap is not new in the upgraded t68m since you have got wap in the "old" t68m too. They just think that people will not be interrested about the revision for the Wap stack.

Thanks for the comments, anyway I think there is no need to maintain 2 version of firmware, since both firmware will be same, just the procedure to flash is little bit difference, and this done by EMMA dongle that reside on every SE service point computer, so technician not doing anything for selection of software part that will be flashed on phone.
I'm not sure WAP 2.0 will be implemented on 68m, since one our friend (Elgato) already using 68i firmware, but he looks like doesn't have WAP 2.0 on his 68m, this because he cannot open correctly WAP 2.0 site like Christersson xhtml pages.
And SE not wrong to tell that both phone will be identical, since they said in "MMS upgrade" context, not "WAP upgrade" context, also like or not SE should mention WAP 2.0 part on their FAQ about T68m conversion if they will put WAP 2.0 on converted version T68m.
Cheers.

Yes Juming you may be rigth...but on the other hand the lab updated sw is probably not the same as the SP updated sw will be. The r380s upgrades to a r380e after a flash of the upgrade program and then you install the r380e phone and application sw in the phone (previusly r380s). There is still r380s sw available on emma but only for not upgraded phones. Once upgraded to r380e you need to update with the r380e sw.

I'm not fully aware of the tecnical side of this,..but CAN wap be upgraded by a software-flash ALONE ?
Wouldnt it need some sort of hardware change ?
I dont really know about this,..but that could be the explanation for not getting wap 2.0 on the T68m.
I'm actually also wondering about the GPRS-part. Can timeslots be upgraded by software-flash alone ?
I'm not that much into these specific tech-parts,..thats why I'm asking about this

This is what SE faq say!!
What are the hardware differences?
Only design and color
Will there be differences in memory size between a T68i/ie and a converted T68?
No, they will have exactly the same functionality and the same memory size.
Does ElGato have the "official" release??....I mean how could he since it's not released yet. Maybe he has some kind of developer release,right??

For WAP, only from version 1.0 to 1.1 need hardware specific update, since it's has different approach (1.0 using SMS as bearer, and 1.1 using Data or CSD to access).
For 1.2.1 it's still can using CSD, in case GPRS not available, so about WAP 2.0 I think.
For timeslot, if the hardware design allow handling timeslot using software parameters, then it's possible, but not all phone using this approach, what I know Siemens using this approach, so someone said that with only upgrade software, Siemens ME45 can handling 8 timeslot simultaneously !
