Wish, If IPhone introduce AWS band

I believe Bell still has CDMA. It's the same situation. 2G (GSM/CDMA) will be around for at least another 5 years. Until it's no longer profitable, they will continue to operate it. Why not? The towers are already in place so they are not really throwing new money in... they are in the collecting mode until that cash cow is fully milked.
^^ But maintaining them is cost though
What kind of BS are you trying to convey? The LG P505 supports HSPA. In fact, this was the handset they launched when they started offering their 100MB data service. I had been using a Nexus One and a HTC Surround using Chatr for a year, connecting on HSPA.
Go back to their old FAQ in 2010, when they first started (and yes, before they offer the LG):
2. Does chatr wireless have a 3G network?
The chatr wireless network operates on 3G (GSM) and 3G+ (HSPA) technology. Unlike the other new wireless companies, it means we've got the benefit of two networks. GSM means great coverage and lower priced phones. HSPA means super fast Internet access.
So there, Chatr supports HSPA on the get-go. So please stop this "Chatr is 2G only" BS.
But I noticed different signal strength on Chatr & Fido connection at same place. Phones were different though. One had 4 and other had 2. But Still I think its tough to maintain two networks in parallel
So the final verdict is that Chatr is also 3G?
But there is a possibility that Chatr started as 3G on 0 day
As others have mentioned, maintaining a 2G network is essential for foreign carrier's customer to roam. They may not have the right 3G band, but many of the phones are triband or quad band that should work.
But are the frequencies same ?
