According to iLounge’s tipster, the next-generation iPhone will come in six versions –three models each with two storage options: (1) standard 3G; (2) “enhanced 3G” (HSPA); and (3) China version. In term of its size and design, still similar as the current model.

…we’ve been told that the next-generation iPhone will come in six versions: two storage capacities each for 3G, enhanced 3G (”3.5G/3.75G”), and mainland China versions of the phone, which will have the same size and general design of the current model, but with a less scratchable matte plastic body. Each of the three versions has been made to match the telecom systems of specific countries, so users in one country shouldn’t expect to have the option between a “slow iPhone” and “fast iPhone.” As before, you’ll get capacity options and different colors.
