Anyone have a good resource other than XDA-Wiki to learn about all the jargon and technical stuff about CDMA/GSM/whatever cell phone technology. (as well as HardSPL, ESDN, god knows what else) I want to have a better understanding of this stuff so I can actually surf the XDA, PPCGeeks, and other forums and find out what I can and cannot use on my CDMA Sprint Diamond, thanks for any help in advance!!
