I am new here and could really use some help. I have a phone that I have purchased to replace a phone I broke last week. I currently am with Credo Mobile whom I really like and they use the Sprint network to use their towers, etc, but the phones they use are specific to them. So my problem is that the phone I purchased on eBay (which does have a clean ESN, as I used to work for Sprint and I understand how important it is to make sure it has that) is a Sprint phone and now I need to have it flashed for Credo. I would appreciate any help that I can get on how I can do this bc I spent 250 on my new HTC Evo 3D and really would hate to have to turn around and sell this to someone else... I have a a Samsung Galaxy S II Epic 4G Touch which I have had problems with, had problems with Samsungs in general lately honestly. I am thankful for all help.
