Can an iPhone give out Wi-Fi for a laptop or iPod touch?

If my mom has an iPhone 4s and I have an Ipod touch nowhere near a Wi-Fi hotspot, am I able to get Wi-Fi through my moms iPhone?

Yes, her phone can be used as a personal hotspot but she has to call the provider to have them turn it on and I believe it is added to the bill.

Yes, if you decide to pay for it. If you want to do it free, jailbreak and download MyWi 5.5.It gives you a Wi-Fi hotspot port and can be used. Hope this helps!
