If you’ve used Identi.ca over SMS, can you please share in the comments which provider you used, which phone, and how the process works?

Here are two entries to get you started:

Verizon Wireless
Blackberry 8830
SMS works seamlessly – all messages come from the same address (XXXXXXXXXX@laconi.ca), so they thread, and I can respond to any message by simply replying to the message on my phone. I cannot tell the difference between “real” SMS messages and Identi.ca messages.
Verdict: YES

AT&T
iPhone (1st gen)
SMS is annoying – messages come from different numbers, so they don’t thread, and you cannot reply to the number and have it post a message. [The different numbers should all tie back to the same reply address at AT&T, but this does not appear to function properly.]
Verdict: NO

(This post will disappear once I collect the necessary information.)
