I popped the sim back in my G1 to check again (FWIW) and same result. There are five specific areas that the N900 reports "no data service" then no cellular service". G1 is solid in one bar areas (if there is such a thing) and works for calls and internet.

I have been getting emails and messages from others that have week 2G, but some seem afraid to be considered naysayers and ostracized from the N900 overlord fans

Never been so torn about a device. Weak 2G and waiting for apps and games while my trusty G1 plays NES, SNES, VGBA and Sega better than the N900 and also plays Genesis, MAME and Final Burn. A lot of MAME and Final Burn are slow on the G1, but the other emulators play great at 528mhz. Nice being able to make calls in all areas near me too.

Still, the potential of the N900 as well as strong web and media keep me hanging on. Also, finding Flash games that play well is addictive A lot of innovative Flash games out there that play fine on 9.4

BTW, the wifi seems to be working better on mine. Medium settings seems to have done the trick.
