Traditional-to-Micro-SIM Cutting Conversion Failure?

Hi everyone, I have gotten my grandma's old iPhone 4 and I my previous phone was a iPhone 3GS. I am unable to switch the SIM cards for the iPhone 3GS uses a normal SIM, whereas the 4 uses a Micro-SIM.
My mum and I have tried cutting it (we saw in a YouTube video that you could just do that and it actually worked for the person in the video) but we have actually cut it a bit too small so now it has space to move around which is bad.
An idea we have is to tape it in place with sticky tape (not on the metal part) so it cannot move. Will this work or ruin the SIM card, iPhone or even both?
Kind regards.

Ignore the "or ruin the SIM card, iPhone or even both?" part.

How much would my upgrade with Sprint cost?

My mom is already entitled to an upgrade from her iPhone 4S and she wants a gold iPhone 5s. We have an iPhone 4 that currently has no service, and she would like to turn that phone on, so that will have an extra cost. But she would also like to add another iPhone 5s to her plan. She would also like a family plan with unlimited talk and text, with I believe 1 GB of data. About how much will purchasing the phones cost, and about how much will her monthly bill be?

Iphone 3 nonstop restore. I've restored 6 times now?

So, my mom's iphone 3 went to that screen with the iTunes signal and the USB pointing at the symbol. You know, saying plug it into iTunes. I plug it in, and try and do a reset, I wait 10-20 min, it resets, acts like its about to be ready to go, and then boom, back to the original backup screen. I've reset it 5-6 times now and everytime it installs all the stuff, then returns to the same screen. Solutions?
