Choosing a new Mobile Tools logo

Thanks to my colleague Ian at Northpoint, who created some nice logo's, Mobile Tools finally has it's own logo! I got 4 different designs and I wanted to hear what you think.

Modules that have their own logo, just give them that extra piece of credibility, ... What does not mean they are actually better:)

So here they are:

1. Simple mobile devices

Mobile Tools small icons

2. Druplicon within mobile reception bars

Mobile Tools reception bars

3. Swiss army knife vertical

4. Swiss army knife horizontal

Same concept, but horizontal layout.
