Do an internet search for MS705-FMEM-174. It will bring up quite a few patchlead options (all from one supplier which which I have no connection, commercial or otherwise). Note that for the Samsung S2 4G i9210 model, there is an explanation of the R1 and R2 sockets: because the 4G uses two connections in parallel to double the connection capacity, it requires two antennas to work fully. R1 is the general antenna connection for a single connection (3G and one 4G), R2 is the additional connection for a second 4G antenna. I've taken the warnings about permanent damage to heart and have NOT tried to use either socket. An internet search for MS147 will bring up other suppliers.
