Java me 无法在诺基亚S60上检索手机id和LAC（在E50中试用）

我一直在努力争取celllid、lac、mcc和mnc。虽然可以找到mcc和mnc，但cell id和lac仍然是空的。下面是代码（根据正在进行的线程数知道它可以工作，但我仍然无法让它工作）

但get Cellid仍受到手机平台、签名证书和运营商的限制：

诺基亚
s40第三版Fp1，要求操作员或制造商签字
S60第三版，FP2（2008年及更新版本发布，不适用于N95等），无需唱歌

我刚买了一台诺基亚S60，带Symbian release 5，我正试图根据手机id，而不是gps来获取手机位置。因此，我使用此页面检索位置，但它与gps不完全相同。但是，要做到这一点，我需要mnc、mcc、手机id和lac，让我惊讶的是，这个开发工具lalchetian说，ice没有给我lac、mnc和mcc。我们这里有一个严重的问题。可能这些属性只在某些设备上可用。
我确认E50无法接收到Cell ID。但我已经编写了一种多平台解决方案，我将在广泛的设备上对此进行检查（>1000台设备在我们的生产环境中）。我从同一个链接得到了原型，但老实说——写这个的人根本不在乎细节

我非常怀疑我的代码是否能在至少一半的设备上运行，但我们很快就会看到它
