This isn't quite Epic-related, but it's unlikely to be a question anyone with a Hero can answer simply because I suspect a huge number of Epic owners were once Hero owners, but few Hero owners have ever replaced a working Hero with a new one. What will happen to my Hero after I activate my Epic (same account, taking over its number)? Will it still boot normally, and just be unable to make/receive voice calls, send/receive text messages, and access the internet over Sprint? Can I treat it like a ghetto-fabulous mini wi-fi tablet, robot controller, picture frame, or something? Or will it detect that it no longer has Sprint service, and refuse to boot into Android? If it matters, the phone's rooted, and running Buuf'ed AOSP, not Sprint's official ROM. Likewise, what happens to paid Market apps (after I've downloaded and installed them on the new phone)? Will they instantly disable themselves, or will they basically stick around forever and just fail to update themselves going forward? I already backed up my text messages to xml... is there anything else anyone can think of that I'll regret not doing in retrospect, or anything I should do while the phone still has service? Likewise, would I gain anything by disabling the phone and network data before I actually transfer the service? Is it safe to assume that network-based location service will cease to work, or is it something that the tower doesn't bother to authenticate, and just answers queries to regardless of activation status on the theory that it would be more work for Sprint to check whether you're entitled to receive location info than to just blindly answer any query that comes in? Actually, that reminds me... if I were to ever want to unroot it for resale to someone, do I need to unroot it while it still has Sprint service? Also, if I'm doing a one-year premiere-customer upgrade, am I entitled to my old phone's permanent MSL code so I can sell it to someone (possibly for them to reflash and use on MetroPCS)?
