I bought my Droid 2 Global a few months ago on eBay (cheap deal as a bad ESN). I've only ever used it with a non-US SIM card here in Europe and also in Canada on GSM. In view of the forthcoming Gingerbread update I have a couple of questions:
Is it likely my phone has been unlocked/flashed before I bought it? How can I tell? Do D2Gs work with foreign SIMs out of the box?
If the phone has been unlocked or flashed, will this affect a possible upgrade to Gingerbread? Will I be able to download the update? If I download it, will it (re-)lock or even brick my phone?
Obviously I don't want to upgrade to 2.1 if I risk bricking the phone.
Any help would be much appreciated. Thanks.
