Apple’s ads are well known for mocking their competitors in subtle and not so subtle ways. The Mac vs. PC ad campaign is perhaps the most well-known example of this. However, the much ballyhooed iPhone 4 Antennagate saga has turned the tables on Apple, which now finds itself at the receiving end of ridicule.

Apple is obviously keen to put the whole issue behind itself. But, its competitors have different ideas. The death grip problem has forced Apple to go on the defensive, and that doesn’t happen very often. It’s no wonder then that RIM, Nokia, HTC, Samsung and others are keen on keeping the discussion going.

The above ad for Samsung Galaxy S, which appeared in the UK press, is an obvious jab at the iPhone 4′s reception problems.
