I had a few friends that went both ways and the unlocked folk endured a lot more cost and pain than the other person that opted for a locked phone. Since we can unlock phones most of the time, changing carriers isn't that bad.
Just wondering why that requirement.
I want to buy a cell phone(unlocked) under $300.I require a phone with a physical keyboard,b'coz i message a lot.Rather you may also suggest touch screens,but make sure that its not easier(faster) to type on them.
I am considering motorola droid pro(found on ebay for 200 usd).
