I like to cuddle my iphone 4s at night. I lay on my left side, and I usually hold it in my right hand. I don't have a lot of friends, so I want to keep the three I have, and I have to immediately text them back if someone accidentally sends me a text message. My worry is the length of the new phone may make for an uncomfortable cuddling experience. I am not certain I will like the feel of the aluminum over my current glass. Will I be able to remove the sim out of my iphone 5 before bedtime and insert it slowly into my iphone 4s and then back into my iphone 5 in the morning? Thank you for your support.
