Unfortunately there is no workaround yet. SMS with "non-numeric" senders (as is the case with most provider originating SMS' and web form SMS') will not show up on the iPhone (at least not on an unlocked US version of it). The cause is not 100% clear yet, but I'd bet it has to do with AT&Ts visual voicemail feature. The way visual voicemail works is that it sends a "silent" notification to the iPhone, which then connects to the AT&T server and downloads the voicemail as a sound file (thus making it possible to listen to voicemails in any order and while offline). I believe this "silent" notification has the same "syntax" as our local provider notification SMS'. Hence, they do not get displayed.

Can't really blame them as the current version was never meant to be used on a non AT&T network. The European version will certainly not have this issue.

Hope this clarifies.
