I have two questions. I have a BlackBerry 8520 and I wanted to switch to an Android phone. I don't have a data plan, so I can't download BlackBerry AppWorld w/o BIS. I was thinking about switching to the Flipout. I don't want to pay for data. So can I download Apps from the Market w/o a data plan, just using wifi? And, can I use this phone unlocked on Tmobile? Thanks!
