Several friends are buying or thinking about buying a Treo 600. So, here is my advice in doing so:
1) First, don’t buy the Sprint phone. It’s cheaper and has good coverage, but is completely unusable as a primary phone. The problem is that when the 1x data link is active (such as when you’re checking email or the web), all incoming calls are sent to voicemail. This is so egregious as to be absurd in a shipping product, and makes the device completely unusable, except as a glorified data-enabled PDA.
2) I highly recommend the AT&T Wireless phone. Until 2 weeks ago, coverage was somewhat poor. However, AT&T just signed a roaming agreement with Cingular as part of their upcoming merger, and so I find the coverage is now superb.
3) Crack the GSM lock as described on my blog or this FAQ. Now, if you’re in a foreign country, you can buy a cheap prepaid SIMM card at any gas station and not pay international roaming rates. (If you want to be clever, you can get an ISP account and configure the phone to dial up over circuit GSM, since prepaid GPRS is not yet available.) Then, update the firmware to 3.04 to get the camcorder functionality.
4) Top software apps:
a) WebPro is much, much better than the built in browser, since it uses a proxy to drastically reduce download time and displays incrementally as the page is loading.
b) I use Good software for complete integration with Exchange. It works great but is very expensive. My portfolio company Sproqit should have a Treo-compatible single-user Outlook-connected product soon. I understand from Walt Mossberg that for POP/IMAP, SnapperMail is the best software.
c) Ptunes. Buy the deluxe version, as being able to use shoutcast to listen to tens of thousands of radio stations around the world is particularly cool.
d) Audible for the Treo
e) zLauncher is a replacement application manager that moves applications to the SD card with a single click. This is essential if you want to install extra software and not run out of memory.
f) Bob’s Clock to make the device an alarm clock. (click files under the Yahoo Group for pay $5 through Handango.)
g) PdaNet
h) miniSync cable
g) Zap!2016, Tetris
