I am at the very beginning of the BB way so I have some Qs )
I have purchased bb 7230 unlocked (seller advised that there is no sim lock and no net lock) from eBay.
I live in Estonia and unfortunately there is no carrier supporting BB data plan or whatsoever. But as far it is unlocked I can still use it for calls and messages as well as a good data keeper and scheduler.
When I check the status it says 3.7.121.
I was wondering if I download the latest software and manage to install it on my BB will this unlock still be there or my BB will return to its original T-Mobile state and be locked again?
Hope I am not a pain in my enquiry)))
