Thunderbolt is about their only phone worth switching to currently.
As far as the android vs iPhone. That one is up to you. I personally could NEVER own an iphone. However I tried, sadly, to push my dad towards one as I thought it’s battery + ease of use would be a good combo for him. HOWEVER with you already having had android I think you would have a hard time switching to something you have less control over. JMHO.
Biggest problem is the carrier. Not sure why but Verizon seems to pick up “new” phones that are slightly retooled versions of some other carries phone last year. But I know they have great coverage and LTE so maybe in the next year or so they will keep up more on their phones with there 4G. I’m a sprint guy so I get phones that are 1st of it’s kind on the crappier of the two 4G systems. can’t have it all. can you?
