Hi All, I am looking to flash an EVO 4G to Boost. I have some ?? hoping you guys can answer If I want to change the number at a later time is it necessary to have the original doner phone? Would it be advisable to keep that phone for future purposes? Some one told me that there are problems with apps working after flashing. Can I please get some comments on this? I don't want to do this and then find out that the apps don't work. We use a lot of apps for business purposes. Will a phone with a bad ESN work for flashing? What should I be careful of there? What other gotchas! do I need to look out for? Your comments and assistance are greatly appreciated.
