cell phone technologies
Boost Mobile / Nextel is phasing out their IDEN network. I've already noticed reduced coverage / signal on my phone. So I'm looking for a new phone and researching the options. Page Plus Cellular looks the best so far. Their coverage map (apparently they use Verizon) is quite good, and they have inexpensive prepaid rates. I'm still debating how much data I'll want to use if I get a smart-phone, and whether a different carrier might have better data rates. And I'm debating whether I should get a small tablet rather than, or in addition to, a smartphone.

Qiao was given an iPad as a gift. I've been wondering why the display says "AT&T" in the upper left corner, even though we're only using it via wifi, and we don't have a contract with AT&T. I looked at the Apple website, and it indicates that there are basically 3 kinds of iPads: for use with wi-fi only, or wi-fi plus AT&T, or wi-fi plus Verizon.
The AT&T version won't work on Verizon, and vice versa, because each network uses different technologies. The next link explains it pretty well.
What’s the Difference between GSM and CDMA?
