Apple says a second wave of iPads will reach customers' homes and U.S. stores on April 30.
Apple Inc. started selling its new touch-screen tablet computer in early April. It can connect to the Internet using Wi-Fi.
The new models will be able to use cellular connections as well and will cost $130 more than the Wi-Fi-only versions. The least expensive has 16 gigabytes of storage space and will sell for $629. The most expensive, with 64 gigabytes of storage, will cost $829.
The new models can connect to AT&T Inc.'s mobile data network. People can pay for the data plan one month at a time.
Apple says people who pre-ordered the 3G iPads will also receive them on April 30.
