iPhone 4 Sim card problems

[Beaner1]

I've had my iPhone 4 since a month after launch date and today was the second time that all of a sudden my screen said there was no sim card installed. In Apple's infinite wisdom, no sim card removal tool was included with the IPhone 4. Luckily I happen to have something small
Enough to shove in and after re-booting my iPhone several times it finally recognize the sim card. Is anyone else having this problem?

Perhaps you should contact your provider and request a new sim card. If that doesn't help my iPhone 3G needed to be replaced for the same issue.
