There's so much to learn! The current state of wireless affairs could be offered as a full-credit university course. There are the phones 'operating systems', the technical information about the ongoing development of transmission, and all specifications of each phone. There is more than enough to keep me busy here. I hate to keep referring the the wonders of the Internet, but I am still in awe that I can do all this research while sitting in my own living room (in my underwear if I choose). It's absolutely free save for the monthly broadband bill. What a profound change in how education can take place compared to the days when I was in college! All this 'you-young-uns-are-sure-lucky-nowadays' attitude must be surfacing because I turned fifty last month.
Still I am becoming quite a cell phone expert thanks to the web. So, I'm here if you have any questions about apps, GMS Bands, Android, HSPA, or unlocking. I would love to share some of my brain's most recently-stored information.
