I was thinking it could (also) be an allusion to 5 complete years of the iPhone.

It can't really be by years:

1: iPhone (2G)

2: iPhone 3G

3: iPhone 3GS

4: iPhone 4

5: iPhone 4S

6: iPhone 5?

The original iPhone debuted in 2007.

Try again! It is going to be the announcement of 5 new lawsuits against Samsung which will be left as a shadow of its former self.
