[sk8r1230]

ok so i have the iphone 4(obviously) and the newest firmware. the phone connects to wifi no problem and shows the signal in the upper left corner at full strength. i find that when i have wifi but no cellular service the phone wont let me navigate the web/send email etc. am i wrong but shouldnt the wifi work seperate from the cellular service?? any help would be appreciated!! thanks!

That sounds very weird.
Did you try it on a few different wifi's to make sure its not a router issue that needs to be restarted?
Cellular service shouldnt make any difference connecting to wifi.
Put the phone in airplane mode and then try to connect to see whats up.

I connect to my job's wifi with no problem and I'm on airplane mode. Make sure that the wifi is working. If it's a public wifi make sure that you've agreed to TOS or paid to access it.

It should definately work even if there is "No Service". At my house I am on the edge of no coverage and Edge coverage so I will randomly get "Searching" or "No Service" and never have any problem with Wifi service.
