Thanks for the link. Once setup, is there any drawbacks to using the Nokia 822 on an AT&T MVNO vs using something like a Nokia 820? Would the 822 be limited to 3G while the 820 could use 4g hspa+? (I really don't care about speed. Just wanted to know if this would be a difference)
Would the Nokia 822 actually be a better choice since I'd have an option to moving to a Verizon MVNO down the road if/when they start letting LTE phones on the network?
Thanks
