Iphone and lag

i just wanted to know if anyone has the same experience:

when i hold my iphone (3GS) with both hands and play with thumbs i cover the whole back and sides of the phone with hands. when i do this it semms ping going up and have spikes sometimes.

when i hold the phone just with the top of thumbs/middlefingers and play with the index fingers ping remains more constant green.

is it just coincidence or someone have same?

I'm using same device and never have occurred shuch problems.
(when playing with both thumbs)

If your using WiFi I would make a directional WiFi antenna like I did! It works great just Google it and you'll see how to build one. Anyways I hope this helps.

I modified mine due to the size of my router.
