According to Flexispy support:
FlexiSPY spy phone downloads directly into the Target phone. FlexiSPY is not a virus and there is no remote install without human interaction. However, you only need access to the Target for the initial install. All settings may be changed remotely (except for introductory iPhone “Basic” versions).
Flexispy LIGHT captures SMS, Call Logs, and Email received directly to an inbox on the phone, and Location using Cell ID (GSM networks only). All iPhone products also include GPS Location. This information is sent to your private web account as part of the service, using the Internet connection on the Target. Any events that occur after installing the program may be captured, even if the Target user deletes them from the logs afterwards.
PRO does everything that LIGHT does, and also has Spy Call remote microphone to monitor the surrounding area (conversations in the room, etc). The BlackBerry version of Pro also includes GPS cell phone Location tracking for enabled devices (network must allow GPS access by 3rd party software).
PRO-X includes all of these features but also adds the Intercept Call, which secretly patches you into any live conversation happening on the Target, in real-time. It also captures GPS coordinates on integrated GPS devices (network must allow GPS access by 3rd party software). CDMA networks don’t support Flexispy PRO-X. SpyCall and Intercept Call are network phone calls to the Target, which FlexiSPY automatically answers without ringing or vibrating, without showing any Caller ID and without keeping any records in the Target phone’s call logs. To avoid possible detection by the other parties hearing you – you need to mute the mic on the Monitor phone.
Flexispy Light, Pro and Pro-X are offered as a one year subscription based product, including a private web account for online storage of all captured data and Target phone history. A 10-day mp quibble money back guarantee and premium level tech support is included for the duration of the subscription period.
FlexiRECORD can automatically record the audio of all Target conversations onto your PC for later review (requires Pro-X already running on Target).
