I’ve spent 73.6 minutes over the last two days looking at various ways to get a photo from my iPhone onto Twitter. As such, these results are definitive, final and no amount of comment spam will move you up on the list!

• TwitPic

Pros: Simple. E-mail your photo direct from your iPhone camera app; photo appears in tweet within minutes. Cons: None that I could find.

• Twitxr

Pros: As simple as TwitPic. Cons: Terrible, terrible name. How do you pronounce it again? Also, it seems like there’s too much emphasis on the Twitxr website, and not on the integration.

• Utterz

Pros: This appears to be the swiss army knife of photo-to-social-networking services. Cons: Too complex: Disqualified.

• Twittergram Flickr to Twitter

Pros: Super-simple – once you get your iPhone-to-Flickr support set up. Cons: Isn’t this Dave Winer’s thing?

• Flickr2Twitter / rss2Twitter

Pros: Indirect integration with Flickr, which is nice. Cons: slightly complex setup steps. This is essentially the same concept as Winer’s Flickr-to-Twitter mentioned above, with you doing more of the work.

• Natuba

Pros: Simple. Cons: No Twitter integration. Disqualified.

• SnapFoo

Pros: Simple, plus has some anti-spoofing measures. Cons: Some of their bio pictures look like ones you might get from marryaprisoner.com.

• Mobicue

Pros: They’ve hired a graphic designer. Cons: They didn’t hire a UX person. Disqualified.

CONCLUSION: Go with TwitPic for now if all you want/need is iPhone-to-Twitter support. If you want to use Flickr as your storage mechanism, use Twittergram or roll your own mechanism based on the same concept.
