Having both a tft and oled san francisco, ive spent some time and i prefer the oled. But, both are a little lacking in volume for music. So the tft can go, to make way for a phone with a better mp3 player. most likely anything sony i think should do it, but will listen to most offers.
Needs to be o2 or unlocked.
The san fran is a tft, unlocked, rooted and running jellyfish 2.2 froyo, boxed in pretty much mint condition.
Should add, wouldnt mind a 2g iphone
