Hello forum,

Like many of you I received my Galaxy S6 yesterday. After turning it on I naturally check the XDA forum to see if anyone had obtained root. I didn't realize that root may not even be possible, not to even mention custom ROMs. I wanted to know if it would be advisable to go and buy the T-Mobile version, should I buy an internationally version, or should I wait and hope the boot loader can be unlocked? I really miss Cyanogenmod on Samsung device for a true super Nexus experience like how my GS3 was. Unfortunately, I bought the GS4 and had my boot-loader locked down so the best I could do was Safestrap and the Google Play Edition Rom by Joe-Tech, but I still long for the feeling of the device truly being mine. Another concern is that anytime I had a real issue with the phone, like if I bricked it, or if the charging port stop working I could take it to the AT&T device store and just get a new (Samsung refurbished) phone. My 14 days are ticking away and I don't know what to do, I would really appreciate if some forum members could point me in the right direction. I signed up for the Next program with AT&T at Best Buy when I got it, so how would that be effected if I returned the device. Also, how do I use the menu key, if I hold the Recent key (the menu key) it just the multitasking window?

Thanks,
