I have been using Droid for several years now. In December 2011 I purchased the Droid Bionic for the 4G network VS a complete changeover to the 4S iPhone. If you are contemplating a change let me warn you, that the 4G network is hardly attainable and I reside in a very accessible location only 8 miles from the Pittsburgh International Airport and have never had a connection problem prior.
The 4G is under development so therefore I should be patient and manually toggle between the 4 and 3 when necessary according to Verizon! As it turns out that's all I do IF I want to try and utilize the 4G network. I have taken the Bionic back to Verizon 2x RE this, and have basically been advised "deal with it" the Verizon 4G network is under development! If I had known what i know now, I would have went with the 4S iPhone and saved myself the aggravation. Any feedback is appreciated.
