Possibly moisture on my IPhone 4 lens?

I have had my IPhone 4 for quite a while and after school I walk to the car quite a distance, I have read recently that your phone being in your pocket when it rains can cause a moisture issue on your camera lens but at the time I had no idea. A couple days after that rainy day ( as i'm assuming this is the cause of my issue ) i noticed when trying to take a picture my camera lens was extremely blurry and nothing was really visible in the pictures. I looked at the lens itself and it almost looks like very small scratches and about 90% of the lens is covered with a very fine layer of what seems like crud. I'm assuming its moisture and not some kind of food or anything along the lines of that. The scratches themselves are too small to have such a big impact on my pictures that i'm getting. Is there ANY way that i can get rid of this issue without opening the phone? I've tried a damp cloth with soap, q tip with alcohol, microfiber cloths for glass lens, scraping it with like a guitar pick and nothing has come off and the size of the smudge hasn't decreased at all. A post somewhere else, a person said that there's no way the water could've gotten inside the lens so i'm also assuming the moisture is on the outside. I also think that it's been too long for the "phone in rice" trick to take off this smudge. It's happened approximately 3 months ago. I just didn't think it was really an issue and didn't do anything to figure it out or remove it. If anyone can help, much appreciated. Ty

If your phone is in your pocket and you walk in the rain and your clothes get soaked with water and your phone is in your pocket wouldn't it be natural for the phone in your pocket to get wet because your clothes got soaked in the rain while you walk under it with the phone in your pocket? Huh?

We don't need to read about that somewhere to know all about it do we?

Turn off and put in a bag of rice for two weeks.

First, get the roux started, it will take about 20 minutes to cook. Melt the butter in a heavy skillet over mediumlow heat. Add the flour and stir often, cooking until the roux becomes a dark chocolate color.

Preheat a grill or grill pan to mediumhigh heat.

Meanwhile, toss the chicken breasts in 2 tablespoons olive oil, 2 tablespoons minced garlic and 1 tablespoons spice mix. Grill the chicken until cooked through, taking care not to overcook and dry out the meat. Cool, dice and set aside.
