Put /6 - i/12 into polar form?

Sorry, / means square root. My iPhone doesn't have the square root symbol. I've asked this questioned multiple times now, and I know how to do it if my teacher allowed it in decimal form. I would find the radius, which is 3root2, and take the inverse tangent of /12 and /6. BUT. My teacher wants it in exact form, no decimals. This complex number isn't one of the obvious radians, like pie/6 or something. So I'm really confused.

Sims freeplay cheat doesn't work anymore?

I have Sims Freeplay on my iPhone and I had used this one cheat a couple times.
You're supposed to completely close the app, then change the date on the phone a few years back, then open the game during the "new" year, then close the app again and change the date to normal. This would give me a couple thousand simoleons at a time.

Now it won't work. When I try and open the game after setting the date back, it says it can't connect to the server because it needs an Internet connection. My phone is connected with full bars. I have a feeling it's because of the update it just received. Anyone know how to get around this? Or if there's another cheat that works?

Is this iPhone repair site legit?

I cracked my iPhone 4s screen recently and I've been looking for glass to replace it… I found this site, iphone4parts.com, and on the color conversion kits, it says that they will do free installation with the purchase of parts. I just needed to know if these people are legit, if they will repair my phone without breaking/stealing anything, and if the glass is any good… If these people aren't any good, is there another site you know that has quality glass and good installation services for a reasonable price? Thanks in advance to anyone that can help me out.
