A couple of our readers have written in over the weekend concerned that they still can't activate their iPhone 3G S on AT&T's network. Greg let us know that he was originally assured his Apple Store-purchased iPhone 3G S would be activated within 48 hrs (?!) but now it looks like that's been pushed back another 48 hrs -- or 4 days total.

He forwarded us an email he claims to have received from Apple offering a $30 iTunes credit by way of apology.

Isolated incident or is anyone else experiencing the same problem?

Full text after the break!

Dear Apple Customer,

Thank you for your recent Apple Store order. We appreciate your patience and apologize for the inconvenience caused by the delay in your iPhone activation.

We are still resolving the issue that was encountered while activating your iPhone with AT&T. Unfortunately, due to system issues and continued high activation volumes, this could take us up to an additional 48 hours to complete.

On Monday, you'll receive an email from Apple with an iTunes Store credit in the amount of $30. We hope you will enjoy this gift and accept our sincere apologies for the inconvenience this delay has caused.

Thank you for choosing Apple.

Apple Online Store Team
