Danger will release a beta version of the public SDK for the Hiptop/Sidekick next week. It will be available free to "registered developers" here.
The Handspring Treo 180 seems to have disappeared as I figured it would. At $99 (w/ service activation), I assumed it was a clearance sale. Now I either need to buy used, or wait for the 270 to drop in price, which will probably take a while...
Same here. I've been using a Visor Phone for a long time and wanted to upgrade to the Treo 180. I don't really need a color screen for the Palm functions.
I checked with some of the T-mobile shops in NY City and they don't have any Treos yet.
