I have a Magic Jack and its GREAT to have. i got it for business stuff i do online, without having to give my cellphone number off. What i do is when im available i have the magic jack going through my computer to a household type phone, and if someone calls ill answer it. While at night or if i don't want anyone calling the magic jack ill turn it off, and that puts incomming calls strait to my magic jack voice mail. What about a APP that puts the magic jack program on your cell phone? It uses you DATA, which is unlimited anyway.... to make calls anywhere in the USA for FREE, and that would also use your magic jack phone number if dialed out. So this would make magic jack users mobile, its like having 2 phone numbers to one cell phone. OF course there would need to be a way to disable the magic jack app so if you wanted that number to go strait to VM it woudl not ring and bother you. Someone let me know if their is a MJ app???? the only thing i know of thats kinda similar is SKYPE, i have it on my phone and when i try to dial a USA number it says itll use my verizon calling plan and thus using my cell phone number which i dont want to use for internet business. THIS APP WOULD BE GREAT, id actually buy it lol. Anyone else like to have a cell phone AND a different phone for business ???
