Apple's iPhone plans this year could trigger shortages of flash memory for everyone, iSuppli says in a new study. The analyst group expects the average iPhone to carry over 35GB of storage after capacity upgrades across the line, or more than the 32GB maximum available today. Combined with a nearly 32 percent growth in iPhone shipments to 33 million, Apple's sheer dominance of NAND flash memory could lead to "periods of undersupply" in the rest of 2010.
