How to delete contacts from iPhone? - 1

I just updated from an iPhone 3 to iphone 5. Some contacts that have come over from iCloud won't delete.

What should I know before buying a second hand iphone 4?

So I've found a good deal for an iphone 4 but the thing I'm worried about obviously is getting scammed. I'm pretty sure it's not a China product but what I'm worried is things like if the iphone 4 is unlockable or not, the IMEI is blacklisted(do i have to worry about this too?). What other factors should I include when buying this?

Is it worth upgrading from iPhone 4 to 5?

Iv had my iPhone 4 for 2 years once November is here and I'm just wondering if it's worth the update? Keep in mind I have not updated the apple software on my phone because it won't work when I try so I'm still using IOS 4 (something like that). I know it's slower then the 5 but I don't care about first world problems. To me a phone that perfectly loads a website in 3 seconds is fine with me.

Persuade me. Why should I Upgrade to the iPhone 5?

How to enable location services with the iPhone?

My dumb boyfriend chose the 'no' option when the iphone asks you to know your location. Now it is telling me to go to settings > general > location services. The only problem is that tab does not exist, when I go under general the 'location services' tab does not exist. What do I do?

THUMBS DOWN to anyone that says go to the general > location services tab. Again, THIS IS NOT AN OPTION FOR ME.

How to transfer from my computer downloaded iPhone apps?

I've just had to restore my phone, re-jailbreaking as i type this. I no longer have all my apps that i got from Installous. Can i just download the apps from wherever on my computer, then use a program to install them, eliminating the need for installous?

Is that possible, or am i to spend hours upon hours trying to get them all from installous?

Sorry about poor spelling and what not, trying to kill a mozzie.
