I was one of the early adopters for the HTC Thunderbolt and got an unlimited 4g data plan. The phone quickly got a reputation for being a lemon. It actually worked fine for me the first year, but I eventually started having problems with the data connection. Took it to Verizon and they actually replaced the phone with a Droid Razr, free of charge! So basically I've been grandfathered into a 4g unlimited data plan with the Droid Razr the last few months, and for the most part have had a good experience. But now, I'm eligible for an upgrade, and I'm pretty sure I lose the unlimited data plan if I upgrade. Sooo my question to the forum is.... What phone would be worth paying $100-200 AND losing the unlimited data plan to upgrade to? I've been using far more than 2 gigs of data a month, although I don't use wifi at all so using wifi may cut down on that somewhat. I'm also pretty happy with the Razr, I don't really see a need for 4 cores and I hear Jelly Bean is buttery smooth but ICS seems smooth enough. What feature would make you want to bite the bullet and upgrade? 720 or 1080 HD screen? More battery life? Wireless charging or NFC?
