Well my Verizon contract is up, and I just got done reading about the new
Palm Centro. I've been pretty happy with my current Treo 650, and would like to stick with Palm. The only thing is that the Centro is only officially available through Sprint ($99 which isn't too shabby). I had them a long time ago when their coverage wasn't all that good, and was wondering how thay stand up to Verizon.
Also for all the Apple folks out there when is the iPhone 2.0 due out?
I've owned phones with several different carriers, and I've also gotten to observe my trainees' use of their phones as we travel the country... So, I can give you a good idea of what the "nationwide" coverage really is.
Sprint: SUCKS. Part of that is that their customer "service" made me HATE them, but they have large gaps in their coverage. You'll be fine, even good, in big cities but as soon as you're in a traffic-jam-free area, you'll be entering what a Sprint-using friend of mine calls "The Sprint Free Zone." He'll even call me from Nebraska to say "Hey, I'm in Nebraska and headed to California, I'll call you in a couple days when I get signal again."
Alltel: The only company that manages to have worse "nationwide" coverage than Sprint.
Verizon: Coverage-wise, pretty darn good. Verizon is one of only two carriers that I feel have true nationwide coverage, with very few gaps in very VERY rural places. However, Verizon works best if you're standing still. Their network botches a LOT of hand-offs.
AT&T: The other carrier with true nationwide coverage. The only big gap I've found is about the western 60 miles of Montana. I still do drop calls, but I drop noticeably fewer calls than I did with Verizon.
Nextel: Haven't used 'em since the Sprint merger. Their coverage is probably better now, but see "Sprint SUCKS" above.
As for the "iPhone 2" you will NOT see one before Macworld Expo in Jan. 08. I expect that the first change you'll see hardware-wise will be a move to HSDPA ("3G") from EDGE, but that won't happen until the 3G chips have significantly reduced their power consumption.
It's kinda funny, so many people have speculated so much as to what will be in the 2nd-gen iPhone, it's gotten crazy. I saw one post on a medical message board where a doc said something to the effect of "I'm waiting for the 2nd-gen iPhone because I hear it'll have a built-in defibrillator."
