How to surprise someone with a new cell phone for xmas?

I have purchased my husband a new cell for xmas, and I think he might have clue of what I have gotten him, but I want to trip him up so when he goes to unwrap what he thinks is a cell I want to throw him off and then suprise him with it.

Any suggestions?

i also got my bf a cell phone. although he thinks he knows i got it, he is not sure. so what i plan on doin is actually hanging it in the tree, like a ornament or something. closer to the inside of the middle of the tree. let him open up the other gifts i got him, so he will see he didnt get the phone, then wait about 2 hours, and call it. he will notice the ringing is comeing from the tree, and he will find it there. it is going to be good lolHow to surprise someone with a new cell phone for xmas?
Call him/her with your mobile to the number of the one you bought for the gift (as if you call someone else) just a moment before she/he opens your gift package.How to surprise someone with a new cell phone for xmas?
Buy him a new pair of jeans. Put it in the jeans pocket. Wrap up the jeans. Call the new phone while he's admiring his new jeans.
