android - getNeighboringCellInfo() returning null list

Question

I'm struggling a little trying to get neighbour cells info (for the current cell info, everything works fine):

mTelephMgr=(TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
neighbours=mTelephMgr.getNeighboringCellInfo();

I've tried with 2G/3G networks, with Galaxy S (2.2.1) & Nexus S (2.3.1), and two different carriers but I always get an empty list for neighbours. The networks are GSM based (Spain).

I've been googling for a while, and whereas some people are reporting the same issue, other seem to have the function working perfectly.

Any suggestions?

Many thanks in advance.

This is not a phone brand issue, the reason is that using a 3G connection you can't get any neighboring cell info (returns an empty list). You need to switch to 2G to get it.
