You may have heard about the upcoming cell phone insurance service that will soon be available through AT&T, but there is one very interesting tidbit that you may not have heard about. If you happen to opt for the insurance and then you decide to drop your iPhone into the toilet, you’re completely out of luck. That’s because there is no insurance option available for the Cupertino cell phone.

As it stands, there will be two tiers to the AT&T cell phone insurance plan. Both options cost $4.99 a month and offer the same kind of coverage. The difference between the two tiers is in how much the deductible is to replace your mobile phone. On the first tier are most standard phones and these come with a $50 deductible. On the second tier are what AT&T call “high end phones” and PDAs, and these come with a $125 deductible.

I find it strange that AT&T is willing to cover some expensive PDA phones, but they show no love for the $399 Apple iPhone. Also note that insurance — which comes out on June 2 — is only available for new contracts and on phones purchased within the last 30 days.
