I bought an unlocked android phone at Amazon and it works perfectly. This phone in particular doesn't have any OS updates I could do (Motorola Defy), so basically I am stock with Froyo unless I flash it with a custom ROM with an newer android version. The phone used to be locked to T-Mobile's network, so my question is: since my phone is currently "network unlocked" if I flash it will it re-lock again?
I appreciate any help and guidance. Thank you.
