I have been with AT&T since iPhone day 1. Am considering jumping to Sprint mainly for the unlimited data. Live in rhode island. Wondering how the service is in the northeast. AT&T has said they would have LTE in the Providence area by end of year. Anyone know when sprint might be in the area. Will I be able to get on day 1? Will I be dead in the water while the porting goes through? Losing the rollover minutes is causing me hesitation. Those really help out when I work from home as I have no land line. Any feedback is appreciated.
