Can you judge my singing? Clips incl?

I'm insanely shy about singing. I haven't sang in front of ppl in years. I'm a perfectionist and I can't seem to get a sense of my voice. I can pick a million things out that are wrong. The only way I can record is by using my iPhone and recording over music playing so sorry about that. Please let me know what you think
Thanks in advance

Added (1). I have found you need to turn the speakers down low for my recording or else there distorted on higher notes. If that doesn't clear some of the nasal sound let me know. I'm concerned it is nasally sounding and I would really like to know if that is the case.

Switching sim cards iPhone 4 to 5?

I got a iPhone 5 from a friend and I have a iPhone 4. My company is AT&T. Can I cut my sim card with a nano sim card cutter and use it with the iPhone 5? Or is there another way

Cydia & Jailbroken Apps Disappeared With 'Evasi0n'?

I just jailbroke my phone last night with Evasi0n v1.3 on my iPhone 4S with the Firmware 6.1.1.It was working last night and I downloaded tweaks, apps, etc., and went to sleep. When I awoke, Cydia and all of my Cydia apps disappeared. The tweaks are still applied and are working & are in the 'Settings', but the apps are completely gone and are unsearchable. I've rebooted regularly, in DFU, and basically every other way and there's no change. I have the same problem with my iPad 2 (also jailbroken from Evasi0n) that runs on 6.1 Firmware… Help!
