Yes it is possible to take your Note 2 from VZW to T-Mobile, Switched weeks ago
Yes it is possible, I've been running on a T-Mobile custom ROM now for the last 8 weeks and going back & forth between VZW and Solavei (T-Mobile).I have been running the Tweaked 1.5 and just recently it updated to Tweaked 1.6 both are for the T-Mobile Note2 sch-T889.
It has been flawless and I never pass up the opportunity to brag about this and show it off to both Verizon customers and T-Mobile customers
as well. The Samsung Galaxy Note 2 is the best Android handset I've ever owned... It will a pretty Awesome Android handset to even come close to the Note2's abilities and excellent engineering.. So a huge Thank You to Samsung and hey "Verizon Suck It" your rule of consumer manipulation and robbery will come to an end one day.... Jerks
