Hi there - Does removing the micro SIM card involve more than just sticking a paper clip in the hole? When I do so, the paper clip seems to just hit a metal wall. Am I doing something wrong?

The SIM card eject hole on the iPhone 4 is significantly harder to press in using a paper clip than the previous model. Just use a bit more force; it’ll open no problem.

According to what I can find on this it should remove the same way as the prior iPhones sim card. A paper clip should be a decent substitute for the sim card removal tool that came with the iPhone. The following article is from Apples knowledge base and has a guide as to how to remove a sim card. http://support.apple.com/kb/ht1438
