Just my experience noted here. Got the X last week. I had ongoing problems with 3G signal dropping to 1x regardless of how strong a signal area I was in. Phone also got VERY warm when accessing data. I'd classify it as hot. I got a replacement today. Very impressed with the quick delivery. Unfortunately the 3G problem remains on this one (it's actually worse) and it gets just as hot. I think there's a real problem generally with the device. I really loved the solid build and phone design. Hopefully a SW fix can eventually solve this for you all. I'm a reformed iPhone (3Gs then 4) user and have switched to the EVO and will hang out over on those forums. Good luck to you all here.
