In my quest for a cheap bluetooth capable class 10 EDGE Phone, I tried T-Mobile’s version of the Samsung SGH-T509 (T509 for short). It is slim, has a good UI and works as advertised. But the geek in me wanted more; like running Google Maps Mobile on it since it is Java capable. Small little problem with that. You see, T-Mobile wants you to buy their games and theirs alone. So they had Samsung rig the firmware to only allow signed midlets to access the network!! There is a deal breaker for me. Unlocking the phone let’s you use other networks but does not remove the T-Mobile customizations to the firmware. In other words, their version of this phone gets the thumbs down from this geek. Phone went back to TMO and I am back on my quest
