I am planning on buying a Tilt in the New Year. Will use mostly as a PDA, great that it is also a phone. I want to be able to use the internet very infrequently. Do I need to buy a data plan thru ATT? Will the built in wifi be sufficient for my casual limited use of the Internet? Will the wifi work w/o having a Data plan with ATT? I just want to take it out of box, use it as a phone and download some apps from Handango website. If not then I will purchase phone from wirefly or letstalk since they only commit you to a 6 month data requirement then cancel the data plan after 6 months. Any suggestions would be appreciated.
