ok i posted this same question on the "Other Carriers (Not ATT or T-Mobile)" section of the forum but i didnt get any reply at all. i hope more people read this section of the forum then the "Other Carriers (Not ATT or T-Mobile)" section and i hope to get some answer.
i have been searching around the web and i have seen people saying they've have experienced the problem but there is no definate answer to my question.

i have an iPhone 3G unlocked with yellowsn0w.
and before the unlock with yellowsn0w, i was on O2-UK pay and go.
3G connection with O2 was great!
but i've noticed that with O2 when i save a picture from safari or email attachments it reduces the quality of the picture.
also on safari when surfing the net image quality on the website are reduced in quality. but when connected to wifi image quality on websites through mobile safari is good. its just like on PC.

but since the release of the yellowsn0w, i have soft unlocked the iPhone 3G and started to use my "3" (Three Hutchison) contract sim which has good 3G signal but i dont always get 3G data even when it shows 3G on and the bars are full(this issue i have always had with 3. even with their legit handset dont get very good 3G data service). when surfing on 3's 3G data, images appear good quality just like on wifi. i wonder if there is some kind of tweak to the iPhones system file to make O2's 3G image quality better?

and another thing is with O2 if there is good 3G signal and go on youtube i get good qulity videos streaming, but with 3's 3G on with good signal strength i always get the "EDGE connection quality" youtube videos. but when i use mxtube with 3's 3G its fine just like O2.

i will later on this year will change contract to O2 from 3.
but from 3 i will missed the good image quality surfing and saving. is there a way to fix the youtube problem with 3 network and image quality problem with O2?

i hope i make sense and i hope there is someone else out there who is going or gone through the same problem and has fixed it or looking to fix it. any information is greatly appreciated.

cheers
