Also have a launch day phone here with no issues, unlocked on day 1 and rooted a few days later. I've had various ROMs and I'm currently running CM 10 nightlies (nightly?)
with the 4.0.4 radios and still no issues. Easily the best smartphone I've owned out of the OG EVO 4G, Epic 4G Touch (SGS2), and Samsung Intercept (briefly).
Sent from a Nexus Galaxy far away...
