In a wireless communication device in which a removable user identity module having a temporary mobile station identity assigned thereto is moved from a mobile equipment having an electronic serial number to a different ME having a different ESN2, a method for ESN rebinding is provided. A second UPS module is connected in parallel with the first UPS module. In this way, a surrounding interference edge is formed, favouring turbulence in the flow and thus a rapid increase in the dynamic pressure. Because as a result of errors in feeding-in, in particular gaps in the incoming conveying stream, it is possible that empty envelopes are produced, in accordance with the invention a transfer device is arranged downstream of the processing means. The present invention also discloses beta-3 agonists of formula I and methods for treating beta-3 mediated diseases and condition using the compounds of formula I, in particular methods for treating diabetes or obesity.
