I have an adroid phone, it's a descent phone and it's not that old yet several times here lately I have ran into problems installing or updatinga a few apps because my version of android is not supported. I think I need to upgrade but I've never done this before. It's a verizon wireless HTC android phone. Is there a way to upgrade from within the android app itslef and keep all of my data or would I need to install a new android OS over this one the way I normally do my Linux OS? If it's the second option how do I make sure my verizon account and phone number are still linked to this phone? Thanks.
