So Im in love with my phone. But im having a problem I plugged headphones in yesterday and now my headphones just slide in and out. No sound works on my phone untill i plug in something into the headphone jack. Then sound only works through the jack. Im not sure what to do No sound works on my phone at all. Should I just take it in.

the fact you say it just 'slides in and out' sounds like a mechanical failure in the headphone jack. The sensor tab that activates when a jack in plugged in sounds like it is jammed, thus no resistance inserting and removing the headphones, as well as no sound (it thinks they are still in)
Either way it is a hardware issue and if it did this without abuse then it is up to Sprint or LG to make it right.

Wanted to jump in and share my experiences. I have the optimus v. same thing happened after only a few weeks of ownership. Looking on the internet, I have found that this is a pretty common problem on all of the optimus models. I have tried everything. Power on/off, battery pull, full restore (even reloading from SD card...)
Would really like more ideas, but I feel like I have done everything in my power... Is there anything I could do to completely reload the OS? (I thought thats what I did when I used the SD recovery) Seems like a completely fresh start could be a good move. Next move is going back to Best Buy, but we all know that is going to be a chore...

That jack has what they call normalling, a spring device that physically connects normal speaker audio when nothing is plugged in and disconnects speaker feed when headphones are plugged in. If the contacts become dirty, it can result in the problem you’re describing. My guess is you spilled something in there and mucked up the contacts...

a quick solution is using an old tooth brush dip it in rubbing alcohol and stick the bristles down the headphone jack and twist it around and try to clean it out the best you can. followed by spraying some duster down there to get everything out. (watch your eyes while doing this)
usually fixed the pre's for awhile.
