The Thunderbolt, by design, you can talk and be surfing the Web when in 3g due to its dual radio chips (but not supported by Verizon). All the 4g phones
seen to have moments of losing the data signal, and I think the Thunderbolt just got that under control from its recent OTA patches! So if you do change, the Razr is dual core, runs voice apps like Iris or SpeakToIt more efficiently, beautiful Amoled screen, so thin and yet sturdy body would make good switch. Look carefully at the HTZ Rezound as it is 1.5 GHz dual core which is tempting too. Oh and the Nexus with Ice cream looks great too. Really, ultimately, its what you need to do with the phone, and will the phone do it the way you need it too should make the choice for you. The choice may be stay with the Thunderbolt, as it does everything just fine, and save the money! HTC said they will give you Ice Cream update on the Thunderbolt in time. Quad processor models should be in the beginning of 2012. You are at least are capable of 4g now...
