1. A method for reliably transmitting information to be stored in a mobile electronic device, comprising the acts of:
- broadcasting multiple copies of data, wherein the number of copies is calculated as a function of an expected error reception rate and a desired fraction of mobile electronic devices to correctly receive the data to achieve sequential exponential improvement in reliability of reception;
receiving at least one copy of the data at the mobile electronic device; and
using the received data to change information stored in the mobile electronic device;
wherein the actual number of copies that must be broadcast to ensure the desired fraction of receivers correctly receive the data is calculated as;
N≧
1+|log P/log(l−
R)|, where N is the number of copies transmitted, where P is the desired fraction of mobile electronic devices to correctly receive the data and R is the expected reception error rate, and wherein the likelihood of reception increases to a high level with the multiple broadcasts.

Abstract
Multiple copies of a software or operating parameter change are broadcast using a wireless signal to a mobile electronic device. Broadcasting multiple copies increases the probability that the mobile electronic device will receive the change without error. The number of copies broadcast is a function of the expected probability that the device will receive one copy without error and a desired probability that the device will receive the change without error.
