A friend just told me that he wants to plug a phone into a portable solar panel, and then put it outside; the phone would then need to take a photo every 5 seconds, and then post those images to a server.

Unfortunately, my only experience with my phone is throwing it against the wall every other day; i.e., I have no j2me experience.

Searching this forum suggests that a project like this is easy enough, but that I have to choose a phone wisely. Which phones make their apis readily available? If I have to store the image on the phone for a short period of time (e.g. connection fails), do all phones make their filesystems available?

I should also mention that there seems to be some play in the specification (sweet! scope creep!); if the user wants to print barcodes for field samples later on from a peripheral, do all phones have the same, err.. peripheral support??

There's a whole raft of Linux phones beginning to emerge, though most aren't available in the U.S. yet. Motorola, Nokia, and HTC all have SDKs (though HTC is .Net, not Java).

Best bet, look for a camera phone (with appropriate pixel resolution) that supports J2ME, and especially the media (camera) JSR - whose number escapes me at the moment.

An IDE is no substitute for an Intelligent Developer.

Thanks for your response, Tim.

I am realizing that finding a phone is a real challenge... I'm also disillusioned with apple, I didn't realize that Steve Jobs is such a git; the lack of j2me support on the iphone is a joke.

Although I'm tempted to glue a phone to a camera, like the guys in the flight of the conchords, do you think that the Nokia N95 is the best solution until the linux cameras improve (gps support, camera) or enter the US market? It has gps and a decent camera. Is there a better value than the N95? (incidentally, this has been edited, since I've found the nokia messageboards).
