^So are you saying the the pics only used up 7 kb each on your phone after they were transfered? Or were they 7 kb on your computer then after the tranfer they actually took up about 50 kb of your phones memory? How many pics do you have on your phone, also how many ringtones and games? Can anyone answer this? Please!

Ok my results (just pm'ed ramsos) :
Alright so the d/l sizes from Safari are as follows :
sm.jpg - 7.7kb
phonebooksize.jpg - 2.7kb
largesize.jpg - 17.2kb
What phone picture info says :
sm.jpg - 7 kb
phonebooksize.jpg - 2 kb
largesize.jpg - 17 kb
Ok now what memory status says menu from the phone says :
sm.jpg - 45kb
phonebooksize.jpg - 19 kb
largesize - 56kb
So to recapituale :
The phone info is the 'real' image size transfered back and forth from the comp to the phone. It will stay the same.
Memory status is what the 'real-real' image size is on the phone. I guess it needs extra memory for the thumbnail and perhaps decompressing the jpeg (which it has to do ahead of time - perhaps it can't do it on the fly)... Hope it helps

dantec thanks for doing the research for me I guess I will come close to my goals with this phone. I will still be purchasing this phone before the weekend, then I can do some more test and post here about them. BTW I am a mac user too and I have heard that this phones works with macs like it was made for them, and that's a cool perk!

ok ... again ...
-the phone stores the image file
plus a decoded, rle kompressed version of that file for faster access
plus a thumbnail of that pic for browsing
-reducing the filesize will help you reducing the overall image(s) size in your phone
-reducing the colorspace and optimizing the picture for rle kompression (octree is just a way doing that) will help ur phone to reduce the size of the rle kompressed version of ur image
.. so either:
small jpeg + "huge" rle kompressed inphone-copy
.. or:
"larger" .gif + "smaller" rle version
rle is a type of kompression where equal pixels are "grouped" to reduce the filesize
you may thest that by sending a gradient file to your phone and a blank one ...

Yup it does work great, with iSync. Sending files. Even answering calls and sms's through address book. You can also easily browse the web on a bluetooth mac with GPRS.

Well I finally got my T616 and I love everything about it, its great, the only thing thats bothering me right now is that I barely get a signal in my house. I'm hoping my signal strength is due to the bad weather were having here, currently i'm only getting up to 16 percent signal strength(according to phone agent). Anyway when I first got the phone it had around 700kb available, but after a master reset I had an amazing 2153kb available! That was great, so now I have 15 custom ringtones on the phone, 3 themes, 4 games, a huge animated gif screensaver, 9 permanent phonebook pics, 15 uploaded pics and almost 300 kb available! Excellent, I love this phone especially picture caller ID and Midi ringtones. As you all know the camera is mediocre at best, but I have a 4 megapixel digital cam so the communicam is just for fun. Bluetooth works perfect and extremely easy with my Powerbook and OSX (Phone Agent, Salling Clicker and Bluetooth conrol panel). The midi dj program is pretty cool too. And I love the golf game. I also have Qbert, Caveman,and Dopewars. This phone is great I just hope my signal gets better, I always had a decent signal at home with my Motorola V60i non-gsm phone. Wish me luck.

These are my findings as far as memory management of Pictures in the phone are concerned.
First, the phone converts the jpeg image to a raw format for purposes of faster loading. This is why your regular 17-20Kb picture becomes 40-50kb on the phone.
In order to reduce the size on the phone, edit the picture in the phone. Yes, it is true that if you edit on the phone, you will get less quality. I found that the "effect" utility in the phone that has the least quality degradation to the picture is the "brightness."
Here's the trick. Before you upload apicture to the phone, edit it's brightness to be only at 60% (in Photoshop). This means that you will make the original picture darker by 40%. I think that's clear enough. Upload the picture to your phone. Then edit the picture in your phone by using the "brightness" effect. The brightness effect will increase the picture's brightness to about an additional 40%. So your end result is a picture that looks about the same as the original. Memory change is from 50Kb down to 36Kb.
Cheers !!!

GSM coverage still sucks in the United States. You just gotta hope it improves over time. I remember when I lived in California and switched from a TDMA phone to a GSM phone, signal was weak and lots of dead spots...

I am so dissapointed with my signal strength, if nothing can be done about this I will have to go back to TDMA because I use my cell phone as my main phone and I can barely use it at home. Often I have no signal and I have not had more than 2 bars of signal strength at home. I am an At&t wireless user and their GSM network is getting new software and they could not help me today, hopefully tomorrow I'll be able to get some help. I love my T616 because of the features but it has to be a phone first, without that its just an expensive toy.
