I‘m not sure why it’s taken so long for AT&T to do this, but they’ve launched an iPhone plan for the hearing impaired. The plan includes:

• Unlimited SMS messages
• Unlimited data usage (email and web)
• $.40 per minute pay-per-use voice
• Visual VoiceMail

and costs $40p/m.

In order to take out this plan you need to complete the forms here. Then you activate the normal way and have to contact AT&T yourselves to change the plan over.
