I purchased a lumia 822 off eBay for ?60 when th gr2 release wasn't out. It was mainly to try out WP8. The phone was great even though i couldn't send texts i just used skype, viber and whatsapp, after gr2 the phone works perfectly. The camera is amazing and loads of people have commented on the quality especially when i say it was ?60. The WP8 app ecosystem is picking up to.
Bought mine off ebay back in May and used here in the Philippines.
It worked like a charm especially after the GDR2 update ironed out the Access Point issue.
