O have both ampkit, and amplitube. Seems like there are more problems with the ampkit link as opposed to iRig, but ampkit customer support is quick to help get you going. Both have noise problem if cranked up in the high gain. You can turn on airplane mode, and use the noise gate. I do get a better sound using an active pickup guitar. If you have amplitube on your iPhone, you have to buy it again for the iPad. Not to sure about ampkit. I do like ampkit better, but wish it had a built in multitrack recorder. They wii add it in a future update. They wanted to get copy paste first. It works great importing into 4 tracks. Lot of potential in ampkit, and good customer support.
convert mp4 to wmv The next iPhone is supposedly going to support HSPA+. And since AT&T has been labeling every single phone that supports HSPA+ as "4G"��
