Accessing AT&T Wi-Fi | Wireless from AT&T, formerly CingularIt's of greater interest to iTouch users and users without 3G access.
- Select 'attwifi' from the list of available networks
- Enter your 10-digit mobile number and check the box to agree to the Acceptable Use Policy. Tap 'continue'
- You will receive a text message from AT&T with a secure link to the AT&T Wi-Fi hotspot. You will not be charged for the text message. The SMS link will only be valid for 24 hours at the location it was requested. Another request must be submitted when using another hotspot location.
- Open the text message and tap on the link for 24-hour access to the AT&T Wi-Fi hotspot
On an unrelated topic I've come across vendor recommendations to reboot the iPhone after every app update - esp. for users with several App Store products. Based on personal experience I think that's excellent advice.
