I used the silver spoon guys. $40 in 36 hours my TP2 is working on boost (got it on the shrinkage as a backup to my sprint TP2 just in case sprint does something nasty
painless easy well worth the $40.
BTW I bought the MIRRO to get the account setup initially. AMAZING phone really. nice clean screen good camera (though only space for 20-25 images) good audio quality (though it has a high pitch whine that I find particularly annoying but no one else here's) and ASTONISHING battery life. 1.5 days still "full" battery.
so if you have a parent or grand parent etc.. that needs a nice capable BT phone with nice but simple hardware and good battery life the mirro is surprisingly nice.
