IMEI unlocks are no longer as cheap as they used to be. The average AT&T unlock price is about $70 if not more depending on your source. Interposers are in now since they cost anywhere from $10 to $30 and works on almost all devices on all iOS's. You'll have to look for an older R-SIM for iPhone 4 support as the current ones are 4S+ minimum, though I don't think it matters at all.
